S3 settings: custom TLS certificates and ignore TLS Errors

When using S3 for synchronization (here MINIO) the server can also use self signed certificates.
This usually leads to an error message.

Similar to WebDAV you could enable in the S3 settings:

  • Custom TLS certificates
  • Ignore TLS certificate errors

Even though both settings seem to be a global configuration, it would make sense to make them visible for S3 as well.

Please note my correponding pull request #8980 for this.
